Coding with Claude Code makes me feel like a teen who just learned PHP again. Unlimited possibilities, but lots of pitfalls.

One of the challenges has been managing context while Claude edits files. It’s tempting to open multiple agents, Slack, or X while waiting—but that often pulls you away from the flow.

@bcherny called it the era of “tending to your Claudes” on a recent pod with @gregisenberg.

What if those pauses didn’t pull you away, but let you think while Claude thinks? And maybe do some squats?

Introducing VibeReps—a tool that launches from Claude Code’s PostToolUse hook and prompts you to exercise during idle moments. It tracks your movement using MediaPipe Pose Landmarker via webcam and counts reps automatically. Claude notifies you when it’s idle or when permissions are needed.

The project is open source and installable via a simple script. Built with Claude Code, of course.

I’ll be honest—I’ve been tempted to keep adding features. But the whole point is to ship and gather feedback. So here it is.

Try it out and let me know what you think!
